Advanced Higher Physics

Use of an appropriate relationship to solve problems involving the energy transferred by a wave and its amplitude.

Use of calculus methods to show that expressions in the form of

E={\mathrm{kA}}^2

Knowledge of the mathematical representation of travelling waves.

Use of appropriate relationships to solve problems involving wave motion, phase difference and phase angle.

y=\mathrm{A\; sin\; 2\pi }\left(\mathrm{ft\; -}\frac{x}{y}\right)

\phi =\frac{\mathrm{2\pi x}}{y}

Knowledge that stationary waves are formed by the interference of two waves, of the same frequency and amplitude, travelling in opposite directions. A stationary wave can be described in terms of nodes and antinodes.
